Radio Wave Reradiation/Reflection TRIZ Cases
- Electronic Device Root-MUSIC Processing for Object Detection
Root-MUSIC constraints on complex-plane solutions improve reflected-wave direction estimates for more accurate object detection.
- Electronic Device CFAR Detection for Stationary Objects
CFAR processing uses signal intensity at zero relative velocity to improve stationary-object detection in complex environments.
- Network-Coordinated Radar Transceiver Scheduling for Lower Interference
A wireless network schedules time-frequency resources for vehicular radar and communications, reducing interference among transceivers.
- Near-range interference mitigation for automotive radar system
An adaptive RLS FIR filter models bumper-reflection and MMIC/antenna coupling interference, then subtracts it to improve 0–15 cm radar detection.
- Radar Axial Misalignment Estimation with Aliasing Correction
Estimated speed-ratio comparisons expose aliasing at stationary reflection points, enabling corrected orientation angles and more accurate axial misalignment estimates.
- Millimeter-Wave SAR Imaging for Sub-Millimeter Surface Wear
Millimeter-wave radar and variable-focus RDA reconstruct SAR images for sub-millimeter wear profiling when dust blocks laser inspection.
- Radar MMIC Context Programming for Smaller Memory Footprints
Sequentially loaded programming contexts let a radar MMIC use smaller RAM partitions, reducing firmware startup time and memory demands.
- Radar Vehicle Localization With Map-Constrained Measurements
Multiple radar measurements and map data filter infeasible positions for accurate real-time localization of moving vehicles.
- Radar Sensor Velocity Disambiguation Using Subramp Processing
Subramp grouping and modified DFT processing resolve radar velocity ambiguity while preserving fine range resolution.
